I know that the branch of Tianjin University of Science and Technology is in Tanggu, but I don't know whether it is in Binhai New Area.
In the university town of Dagang, there are Binhai Foreign Affairs College of Tianjin Foreign Court, Nankai University (which should also be called Binhai College), as well as two colleges of procuratorial and law. Take 186 or 652 to Dagang University Town.
